BACKGROUND

Scabies is a highly contagious neglected tropical disease and a persistent challenge globally, particularly in regions like the Philippines, where it remains endemic. With conventional treatments facing limitations such as resistance and adverse effects, exploring the potential of traditional medicinal plants offers a promising avenue for novel therapeutics. However, evidence of their comparative efficacy and safety is still lacking.

To determine the efficacy and safety of Gliricidia sepium (kakawati), Senna alata (akapulko), and Tinospora rumphii (makabuhay) compared to topical scabicides or placebo in the treatment of Filipino patients with scabies using a systematic review. 

We searched the following databases from inception to March 2024: MEDLINE via PubMed, CENTRAL, EMBASE, EBSCO, HERDIN, ClinicalTrials.gov, WHO-ICRTP, and PHRR. We included all randomized controlled trials involving Filipino patients diagnosed with scabies where preparations containing one of three plants (G. sepium, S. alata, or T. rumphii) were compared with a topical scabicide or placebo for treatment. Two review authors independently applied eligibility criteria, assessed risk of bias (using Risk of Bias 2.0), and extracted data from the included studies. Primary outcomes were complete clearance of skin lesions, reduction of pruritus, and the presence of serious adverse events. Secondary outcomes were recurrence, any adverse events, adverse events requiring withdrawal, and patientreported outcomes. We used RevMan 5.4 to pool dichotomous outcomes using risk ratios and continuous outcomes using mean difference and applied random-effects meta-analysis. We tested for statistical heterogeneity using both the Chi2 test and the I2 statistic. We presented the results using forest plots with 95% confidence intervals. We intended to conduct a funnel plot analysis to check for reporting bias but were unable to because of the limited number of studies. Quality of evidence was assessed using the GRADE approach, and a Summary of Findings table was created using GRADEpro GDT for the primary outcomes.

We included nine RCTs (N=607 participants) that compared various dosage forms (ointments, lotions, poultice, soap, aqueous extract) containing one of the three plants (G. sepium, three studies; S. alata, two studies; T. rumphii, four studies) versus placebo or existing topical scabicides (permethrin, sulfur, crotamiton). Pooled analyses showed that there is probably no difference in complete clearance of lesions between G. sepium and 5% sulfur (RR 0.92 [0.79, 1.07], 2 RCTs, N=85, moderate certainty of evidence). We are uncertain about the difference in complete clearance of lesions between S. alata lotion and placebo (RR 4.94 [1.67, 14.62], 2 RCTs, N=157, very low certainty of evidence), T. rumphii and crotamiton (RR 1.02 [0.76, 1.37], 2 RCTs, N=131, very low certainty of evidence), and T. rumphii lotion and placebo (RR 5.28 [0.76, 36.43], 2 RCTs, N=71, very low certainty of evidence). Data could not be pooled for reduction in pruritus scores due to limited studies for each intervention. No serious adverse events were reported across all studies.

Gliricidia sepium (kakawati) is probably as effective and safe as 5% sulfur in the management of patients with scabies and may be a promising alternative herbal treatment. Future RCTs should compare it with scabicides recommended by the Philippine Department of Health and World Health Organization, such as permethrin, benzyl benzoate or oral ivermectin. T. rumphii and S. alata may also be investigated using RCTs that should be adequately powered and with good methodologic quality.

OBJECTIVE: To assess the value of chromosomal microarray analysis (CMA) for the detection of low-level mosaicisms in amniotic fluid samples, and to retrospectively analyze the rare cases of mosaicisms. METHODS: Chromosomal karyotype of the fetus was determined by G-banding analysis of cultured amniotic fluid cells. CMA was used to detect copy number variation of fetal chromosomes, and fluorescence in situ hybridization (FISH) was used to determine the proportion of fetal chromosomal mosaicisms in uncultured amniotic fluid cells. RESULTS: Among 825 prenatal samples, 4 cases of true fetal mosaicisms were detected, which yielded an incidence of 0.48%. Two cases were sex chromosomal mosaicisms, and two were autosomal mosaicisms, which involved chromosomes 8 and 9, respectively. All cases were verified by G-banding analysis of cultured amniotic fluid cells, CMA, and/or FISH. CONCLUSION CMA has a great value for detecting low-level mosaicisms in amniotic fluid samples, though the positive results need to be verified by other techniques and should be interpreted with caution. The review of rare cases can provide a basis for prenatal genetic counseling.

OBJECTIVE

To determine the predictive values of the TIRADS and Bethesda Scoring Systems in diagnosing thyroid malignancy at the Quezon City General Hospital.

Design: Retrospective Review of Records

Setting: Tertiary Government Training Hospital

Participants: Records of patients aged 18 years old and above who were admitted and underwent thyroidectomy under the Department of Otorhinolaryngology-Head and Neck Surgery from 2018 to 2023

A total of 47 patient records were included, 16 had thyroid malignancy while 31 had benign histopathology results. The Bethesda system showed 60% sensitivity, 94% specificity, 82% positive predictive value and 83% accuracy while the TIRADS system showed 53% sensitivity, 50% specificity, 33% positive predictive value,and 51% accuracy. Using Chi-Square tests, the Bethesda system had a strong association (p value < .0001), while the TIRADS system had no significant association (p value 1.000) with thyroid malignancy [odds ratios 24.2 and 1.00] respectively.

Our study showed that the Bethesda classification had good specificity, positive predictive value, accuracy and fair sensitivity while the TIRADS system had poor predictive value

Hyalinizing clear cell carcinoma of the salivary gland is a rare neoplasm, accounting for only less than 1% of malignancies arising from the salivary gland. It is molecularly defined by the expression of the EWSR-ATF1 fusion oncogene. To date, there has been no previous studies published yet in the Philippines regarding the existence of this tumor. In this paper, we present a case of a 70-year-old elderly female who had a 10-year history of a gradually enlarging left lateral neck mass. Histopathologic examination showed a tumor arranged of cords, nests, and trabeculae of monomorphic round cells with abundant clear to lightly eosinophilic cytoplasm surrounded by thick hyalinized collagen bundles. Immunohistochemistry and molecular studies were done which revealed a positive p63 staining, negative SMA and S100, and an EWSR1 rearrangement in Fluorescence in situ hybridization (FISH), thus, confirming the diagnosis.

BACKGROUND

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma (NHL). Classification of DLBCL is often based on the cell of origin (COO), distinguishing between germinal center B-cell (GCB) and non-GCB subtypes. Although not yet recognized as a distinct entity by the World Health Organization (WHO), double expressor lymphoma (DEL), characterized by the co-expression of c-MYC and BCL2, carries an unfavorable prognosis for a subgroup of DLBCL patients. Another entity is the so-called high-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements (double-hit/triple-hit lymphomas) diagnosed through fluorescent in-situ hybridization (FISH) analysis.

This study aimed to determine the clinicopathologic profile and survival outcomes of Filipino DLBCL patients at the Philippine General Hospital (2016-2021), comparing double-hit versus non-double-hit and doubleexpressor versus non-double-expressor lymphomas, and assessing concordance between FISH-measured double-hit and IHC-measured double-expressor statuses.

This is a single-arm, retrospective cohort study involving all surgical pathology cases signed out, with the aid of immunohistochemistry (IHC) studies, as NHL DLBCL, GCB, or non-GCB subtype, from 2016 to 2021. A second panel of IHC studies and FISH analysis using tissue microarray was subsequently done. Most cases exhibited a nonGCB subtype and were classified as DEL on second IHC panel. Five out of eleven DEL cases were reclassified as double hit lymphoma (DHL).

Clinically, most patients with these lymphomas present at age 60 years and below, exhibit B symptoms, with elevated serum lactate dehydrogenase (LDH) levels, at least stage III-IV disease at diagnosis, and possess a high International Prognostic Index (IPI) score, collectively indicating a poor prognosis.

Survival outcomes for patients with DLBCL ranges from three to 37 months. All cases of mortality were associated with DEL, contrasting with DHL cases which had variable outcomes. Due to limited sampling, statistical significance of the results cannot be determined. A comprehensive evaluation is essential to the diagnosis of DLBCL and DHL to include a complete immunohistochemistry panel and molecular testing, notably with FISH studies.

BACKGROUND

The COVID-19 pandemic resulted in the lack of traditional cadaveric dissection among first year medical students in Anatomy courses in the University of the Philippines College of Medicine. The Learning Enhancement in Anatomy Program (LEAP) was implemented as a bridging program to enhance knowledge and understanding of gross anatomy and histology. As part of this program, a novel multi-strategy teaching method was conducted for the Integumentary and Musculoskeletal Anatomy Module.

This case study described a novel multi-strategy teaching method on Integumentary and Musculoskeletal anatomy for first year medical students which was done after the COVID-19 pandemic wherein there was a shortage of cadavers. By describing this multi-strategy teaching method, this case study aims to present a potential alternative teaching method in a situation where there is an unexpected shortage of human cadavers.

A retrospective review of documents related to this teaching method among first year medical students at the University of the Philippines College of Medicine was conducted from November 15, 2023, to January 15, 2024. The novel teaching method for the Integumentary and Musculoskeletal station was taught using five different methods: proctor demonstration, a prosected lower extremity with a self-directed manual, dissection education videos viewed on a large screen, skeletons for osteology, and individual light microscopes with a self-directed laboratory histology manual. We described the data and analyzed according to strengths and limitations, and formulated recommendations to improve the module.

The Integumentary and Musculoskeletal Module of the LEAP provided an interactive, hands-on experience in anatomy education. The five-pronged method facilitated a multifaceted approach to learning through cadaveric prosections, self-directed manuals, dissection videos, osteology exercises, and microscopic study. There was active engagement, overall positive student feedback, and increased post-test scores. However, certain limitations, such as the lack of direct cadaveric dissection, potential underutilization of histology components, and reliance on faculty guidance, highlight areas for improvement.

The Integumentary and Musculoskeletal Module of the LEAP has demonstrated significant strengths in enhancing anatomical education through a multimodal approach that fosters active learning, improves knowledge retention, and provides a structured curriculum adaptable to various resource constraints. Student feedback and test performance support the effectiveness of the module, particularly in gross anatomy. Addressing challenges in future iterations will be crucial in refining the program and expanding its applicability to different educational contexts. By building on its strengths and mitigating its weaknesses, this five-pronged method can continue to serve as a model for innovative and effective anatomy education. 

Gliomatosis peritonei (GP) is a condition characterized by the dissemination of mature glial tissues throughout the peritoneal cavity. It is usually associated with immature ovarian teratoma but presents with mature cystic teratoma (MCT) in 1% of cases. GP, associated with MCT, is a benign disorder. The majority of cases remain asymptomatic and rarely recur. Here, we present a case of a 22-year-old woman with a history of abdominal enlargement and severe abdominal pain who underwent exploratory laparotomy, peritoneal fluid cytology, bilateral salpingo-oophorectomy, appendectomy, omental biopsy, and Jackson-Pratt drain insertion with histopathologic result of GP with MCT. A month later, the patient had a recurrence of abdominal enlargement, necessitating a second surgery. Immunohistochemistry for histopathologic evaluation and diagnostic imaging are crucial in confirming the diagnosis and guiding the treatment strategy. A multidisciplinary team approach in monitoring and comprehensive support is significant in optimizing outcomes for patients with aggressive GPs associated with MCT. Further research and clinical experience are essential to establish a standardized guideline to improve the management and clinical outcome of this condition.

INTRODUCTION: Hydroxychloroquine (HCQ), originally an antimalarial drug, is currently used to treat multiple disorders, especially rheumatic diseases. Given its good efficacy and safety, HCQ is widely administered in pregnant patients. However, the safety profile of HCQ during pregnancy remains controversial due to limited research. In addition, HCQ has been reported to reduce preeclampsia in patients with systemic lupus erythematosus (SLE) and could potentially alleviate the symptom of preeclampsia. However, the clinical profile and molecular mechanism of HCQ in preeclampsia is yet to be fully understood. METHOD: We reviewed the literature on HCQ treatment in pregnancy with rheumatic diseases and preeclamp-sia in PubMed and Web of Science. We also discussed the safety of long-term therapy with HCQ during pregnancy. RESULTS: HCQ mainly modulates autoimmune response through inhibition of lysosomal function, toll-like receptor (TLR) signalling, nicotinamide adenine dinucleotide phosphate-mediated oxidative stress and autophagy. Benefits of HCQ in treating rheumatic diseases, including antiphospholipid syndrome, rheumatoid arthritis and Sjogren's syndrome during pregnancy, has been demonstrated in clinics. In particular, multiple clinical guidelines recommend HCQ as an indispensable therapeutic drug for pregnant patients with SLE. Additionally, it may potentially function in preeclampsia to improve clinical symptoms. CONCLUSION HCQ is effectively used for rheumatic diseases during pregnancy. The benefits of HCQ treatment in rheumatic diseases outweigh the risk of adverse reactions it induces in pregnant women.

INTRODUCTION: While traditional Chinese medicine (TCM) has a long history and continues to be widely practised, its overall clinical efficacy according to conventional scientific standards remains the topic of ongoing research and exploration. This review focuses on the potential use of acupuncture and Chinese herbal medicine (CHM) in combination with Western medicine in Singapore, based on recently published data on the clinical effectiveness and cost-effectiveness of these TCM treatments. METHOD: We collated and summarised 71 research papers published in the past decade, focusing on randomised controlled trials, systematic reviews and population-based cohort studies that had a total sample size (treatment and control arms) exceeding 60. English-language articles published between 2015 and 2025 were identified by searching PubMed/MEDLINE, the Cochrane Library and the China National Knowledge Infrastructure. The search strategy included intervention terms like "acupuncture", "Chinese medicine", "TCM", "traditional Chinese medicine", "RCT" and "randomized controlled trial"; economic evaluation terms like "cost" and "cost-effectiveness"; and disease conditions of concern. We narrowed our research to the clinical effectiveness and cost-effectiveness of CHM in which either the individual ingredients or the products were listed as Chinese Proprietary Medicines (CPMs). RESULTS: The summary tables demonstrate that the integration of acupuncture and/or CPMs with conventional Western medicine can enhance treatment outcomes across various chronic and non-chronic diseases. Their affordability and preventive focus can contribute to long-term healthcare cost savings, benefiting both patients and the healthcare system as a whole. CONCLUSION With a robust regulatory framework, scientific validation and government support, acupunc-ture and CPMs have an important role in the management of various diseases, especially chronic ones, in Singapore.
